To a l whom it may concern: end of this piston-rod is attached a piston or Be it known that l, CLINTON P. RINKER, a plunger, 0, which is provided with an up citizen of the United States, residing at Mewardly-opening valve, Cook, in the county of Red \Villow and State From the upper side of the cap O, at the ceu 55 of Nebraska, have invented a new and useful ter of the same, projects acylindrical flange, R, Improvement in Pumps, of which the followof suitable height, and formed in the said cap ing is a p fi ation. and surrounding the said flange is an annular My invention relates to an improvement in groove, S, a shoulder, T, being formed between single-cylinder doubleacting pumps,- and it the said groove and side of the cap. 60

The said collar has its inner edge beveled, as Fig. 4 is an enlarged bottom plan view of the at X, the said beveled edge bearing against 70 same. the rubber ring U and serving to compress the A represents a vertical cylinder of suitable latter so firmly against the flange R as to eiieet diameter, the upper end of which is provided a perfectly tight joint therewith, and also with avertical extension, B, which is oflessdicauses the rubber rings U and V to expand aineter, as shown. The lower end of the cylupwardlyavhen the ring is forced down into 75 inder is closed by a cap, 0, which is provided its seat, so as to cause the upper edge of the with a central threaded opening, D. Comring V to project slightly above the upperend inunieating with one side of the cylinder A, at of the flange R. the upper end thereof, is a vertical discharge- Y representsavalvecage, which hasit-s lower pipe, E, which extends to the upper end of edge seated on the rim \V and projecting out 80 the well, and is provided with a dischargeward under the lower end of cylinder A, so spout, F. On the opposite side of the cylinthat when the cap 0 is screwed to the lower der A, and communicating with the upper end end of said cylinder said cage and the collar \V thereof, is a vertical pipe, G, which hasits upare firmly secured in place. From the base per end closed by a suitable cap or plug, and of the cage project vertical arms Z, the upper 85 thereby forms an air-chamber. ends of which are connected by a circular H represents a vertical tube of suitable diplate, A, which is provided on its upper side ameter, which is perforated, as shown, and witha central vertical stem or guide, 13, the has its upper end screwed in the opening D. said stem, plate, arms, and base being formed The said perforated pipe is ineased in a wire integrally, and preferably ofcast-iron. Open 90 0 screen, I, and to the lower end of the said pipe ings are formed between the arms Z, as shown, is secured a plug, K, which tapers downward said openings extending almost entirely to a point, L, that is driven in the bottom of around the cage. the well, and thereby the said plug constitutes 0 represents a sand-valve, the construction an anchor, the function of which is to securely of which is as follows:

On the under side of in the cylinderand has its upperend connected plate B is arranged a valve, F, which is eir- I00 to a handle or lever, N, which is pivoted on cular in form, and is made of leather or other the upper end of the pipe E. To the lower suitable material.

G represents a hub, which is provided with a series of spirally-arranged radial wings, H, and said hub is arranged under the center of the valve S, and it and said valve are secured under the plate D by means of a screw, 1, which passes through central openings in the hub and valve H and enters a threaded opening in the lower end of rod E. When the sand-valve is seated on the upper end of the flangeRin its normal position, the radial wings thereof depend in said flange.

The operation of my invention is as follows: \Vhen the piston-rod is raised, the water is drawn into the cylinder through the sand valve andfllls the lower part of said cylinder and forces the water which was before in the said cylinder into the upper portion thereof until the latter is filled, and the residue is then forced through the discharge-pipe. The air-chamber, being placed opposite the discharge-pipe, receives the pressure equal to the column of water in the discharge-pipe, and when the piston becomes stationary at the upper or lower limit of its stroke this cornpressed air causes the water to flow steadily through the discharge-pipe, and as the cylinder holds alarger volume-of water than the discharge-pipe the air in the air-chamber acts as a cushion and relieves tle cylinder of excessive pressure. When the plunger is lowered, the water in the upper portion of the cylinder is forced through the dischargepipe, and thereby the pump is rendered double-acting, and thereby a continuous flow of water is caused. The sand-valve being provided with spiral radial arms on its under side, said arms are acted upon by the ascending current of water through the pipe H, caused by the ascent of the piston or plunger, and cause said sand-valve to rotate rapidly, thus displacing any substance which might'otherwise remain lodged on the valve-seat, and the valve then settles back to, its place upon the valveseat, and the latter is kept constantly clear. By means of the rubber rings, upon which thesand- "alve settles, the fine particles of sand, scale, or other foreign substances are permitted to remain without breaking the packing-joint between the valve and valveseat, as the rubber ring will be pressed down by the valve, together with the obstruction, until the valve reaches the lower limit of its movement, thus efl'ecting a perfectly tight joint between the valve and seat and preventing the water from escaping back into the well from the cylinder. \Vhen the valve is drawn upward at the next ascending stroke of the piston, any obstruction which might have been pressed down on the rubber valve-seat will be forced to the surface by the expansion of the rubber as the latter seeks to reassnrue its original form, and the obstruction will be again acted upon by the lateral current of water caused by the rotation of the sand-valve.

Having thus described my invention, I claim- 1. The combination of the cap 0, having the central opening and the flange or rim It, the

elastic packing-ring around said flange, the

ring WV, surrounding said packing-ring and having its inner side beveled, the cage having its lower side bearing on the ring W and extending outward therefrom, the cylinder screwed to the cap, and bearing on the extended base of the cage, for the purpose set forth, the vertically-movable valve having the stem E guided in the cage, and the wheel secured to the lower side of the valve and provided with the radial spiral blades, substan tially as described.

2. The combination of the cap 0, having the central opening and the flange or rim R, with the elastic packingring around said flange, the ring W,surrounding said packing-ring and having its inner side beveled, the valve D, having the stem E on its upper side, and the valve cage having the guide for the said stem and the flange at'its' base compressed on the ring W, for the purpose set forth, substantially as specified.

3. The combination, with the cylinder A, the cage having'its lower edge provided with a flange resting under the lower end of the cylinder, the collar YV, bearing under the base of the cage and having its inner side beveled, the cap 0, screwed to the lower end of the cylinder, and thereby securing the cage and collar in place, said cap having the flange or rim R extending through the collar, the rubber packing on said flange or rim and pressed by the collar, and the vertically-movable valve 0, guided in the cage and having its seat on the upper end of the flange or rim, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of twowitnesses.

CLINTON P. BUNKER.
